HTTF-1500 electric furnace is a compact high temperature tube furnace using 99% High Purity processing tube and SiC heating elements as heating elements. Vacuum sealing assembly is included to connect with 1/4" gas hose. The temperature of 1500 vacuum tube furnace is controlled by high precision SCR (Silicon Controlled Rectifier) digital controller with accuracy +/-1°C and 30 segments programmable up to 1400°C.
Laboratory Furnace Structure | Double-layer steel casing with two air cooling fans. High purity fiber alumina board chamber for the best energy saving. | |
Power | Single Phase, 208 - 240V AC, 50/60 Hz. 2.5 KW Max.(20A breaker required) Power cable included, but no plug | |
Alumina Process tube | 99.5% High Purity Alumina processing tube. 2" (50.8mm) O.D x 1.65" (42mm) I.D x 27.6" (700 mm) Length. Two fibrous ceramic tube blocks are included for blocking heat radiation from the inside tube. | |
Vacuum Flange & Optional parts | One pair of SS 304 vacuum flange with double high-temperature silicone O-ring is Included Two-needle valves with 1/4" pipe adapter are installed with the flange 2" default flange with 1/4'' Bard fittings, 1/4'' tube feedthrough port (for 1/4" O.D thermocouple insert) and a KF25 vacuum port（click bottom right picture to see details ) One Vacuum/ pressure gauge is installed on one side of the flange The angle valve is not included, please order at extra cost. The vacuum level can reach 10-2 torr by a quality mechanical vacuum pump and 10-5 torr by a molecular pump. | |
Pressure Measurement / Monitoring | Mechanical Vacuum Gauge (included ）This mechanical vacuum gauge measures within a pressure range of -0.1 to 0.15Mpa. | Digital Pressure Gauge (optional) |

Temperature Controller | YD518P temperature controller is included. Proportional–integral–derivative control (PID control) and auto-tune function 30 segments programmed with ramping, cooling, and dwelling steps Built-in over-temperature alarm and thermocouple failure alarm +/- 1 ºC temperature control accuracy | |
Recommended Heating Rate: | 10°C / min (RT~1000°C) 5°C / min (1000°C~1500°C) | |
Heating Zone | Heating Zone Length: 6" (152 mm) Constant Temperature Zone: 60 mm (+/- 3°C) Temperature Accuracy: +/- 1.0°C | |
Heating Element | SiC rods, 4 pcs, （ Click the picture below to order a replacement or spare one. The heating element is consumables. Please click the picture below for detailed specs and order spare. For the SiC heating element, the Resistance change with life, please replace the aging rod properly. | |
Dimension: | 400 x 300 x 530 mm (15.7" x 12" x 21") | |
Net Weight: | 120 lbs | |
Shipping package size | 48" x 40" x 40" | |
Shipping weight | 165 lbs | |
Warranty | One-year limited warranty with lifetime support (Consumable parts such as processing tubes, o-rings, and heating elements are not covered by the warranty, please order the replacement at related products below.) | |
Laptop, software & WiFi Control (Optional) | Brand new laptop with Microsoft Windows 10 and Microsoft Office 2013 (30 days free trial) for immediate use. Labview Based Temperature Control System) enables users to edit temperature profiles, manage heat-treatment recipes, record, and plot data for MTI furnaces. A wireless remote control provides up to 300 meters of operating range. The above features are available upon request at an extra cost (up to $1,000). | |
Attention Notes | Performance degradation (i.e. furnace cannot reach the maximum temperature of 1500°C or it is drawing a higher than normal working current) can be expected due to the use of aged SiC heating elements. It is necessary to replace all the heating elements if the above symptoms were seen. Please order the replacements from the standard package list in below. | |
Warnings | The tube furnaces with alumina tubes are designed for use under vacuum and low pressure < 0.02 MPa Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. The flow rate for gasses should be limited to < 200 SCCM (or 200ml/min) Vacuum pressures may only be safely used up to 1500°C | |
